| 摘 要： | 内部故障暂态仿真计算对快速继电保护来说十分必要，文中对三峡发电机内部故障的过渡过程进行了仿真，并将计算结果与稳态仿真程序的计算结果（其正确性已得到验证）进行了对比，验证了大型水轮发电机内部故障暂态仿真程序的正确性，为探讨内部故障暂态时各电气量的变化规律、寻求性能更完善的保护方案提供了依据。

| Abstract: | Generally speaking, the steady-state analysis of stator's internal faults in large hydro-generators has been solved. Since the transient behavior analysis of internal faults is necessary to fast relay protection, in this paper it is simulated on the Three Gorges Generator for the first time. And the calculation results are compared with the results obtained from the recognized steady-state simulation program, which verifies the correctness of the transient calculation. This paper is helpful to discuss the varying regularities of transient currents in case of internal faults, and supplies the foundation for improving the protection schemes. |
